Re: [R] Indifference curve

Hello, Is this it? u <- function(x, y) 3*x^2 + 2*y x <- seq(-10, 10, by=1) y <- seq(0, 150, by=1) a <- c(100, 200, 300) persp(x, y, outer(x, y, u), ticktype="detailed") contour(x, y, outer(x, y, u), levels=a) Hope this helps, Rui Barradas Em 28-06-2012 10:13, Akhil dua escreveu: Hello eve
